Sweet and Spice Popcorn

(I had to double the ingredients to pour over my popcorn)
BEWARE-this is addictive! So simple and yet so delicious!
• 4 quarts popped popcorn
• 3 tablespoons butter or stick margarine
• 1/4 cup sugar
• 1 tablespoon water
• 1 teaspoon ground cinnamon
• 1/4 teaspoon salt

Place popcorn in a large roasting pan coated with nonstick cooking spray. In a saucepan, melt butter over low heat. Add the sugar, water, cinnamon and salt; cook and stir over low heat until sugar is dissolved. Pour over popcorn; toss to coat. Bake, uncovered, at 300 degrees for 10-15 minutes. Serve immediately.
